Banded Racer | Argyrogena fasciolata Shaw, 1802
Argyrogena
fasciolata commonly called as Banded
racer is a snake species of family colubridae under the
genus Argyrogena. It is a small to medium sized snake having
smooth scales where young ones are blazingly banded while the adults
are unvarying and without having any pattern. Thus it can be easily recognized by just checking
the presence of white bands of zigzag manner bordered with black color over the body in case of juveniles.
Snout in these snakes is curved and prominent where
rostral is large, somewhat broader than wide; suture are between the intranasal
scales; frontal nearly as long as its distance from the end of the snout, or as
the parietals; supra labials 8 - 9; where 4th & 5th are in the contact of
eyes; 5th supra labial in these snakes is larger in area which touches the lower
anterior temporal scale; preocular is one; pre-sub ocular in some specimens may be 1 or absent; Loreal scale
is 1; Postoculars two and temporals 2+2,
2+3 or in some 3+3 also. Lower labials 9/9
and are in connection with the anterior chin-shields; chin-shields of posterior
portion are almost similar in length of the anterior one, disjointed from each
other by 2-3 series of scales.

Nepal, Pakistan and Sri Lanka. Dispersed in varied range of forests including
dry deciduous, mixed deciduous, scrub, grasslands, semi-desert and hilly dry
lands. Also found in drier portions of its range such as rocky terrain,
agricultural, gardens, domains having dense vegetation , rodent holes, rock crevices, bushes, under leaf litters and
under the roots of old trees.

Threats include
the killing of these snakes under misidentification with venomous snakes &
by way of road transport in all parts of its range. Besides, habitat destruction
is also the rising threat for the species as the preferred living habitat of
the species is getting reduced because of severe over-grazing and clearing
of vegetation
